Agoda is the largest and fastest growing online hotel booking platform in Asia, and as a Priceline Group company, we are part of the largest online travel company in the world. We understand the value of a great mobile experience for our customers and are constantly investing in mobile app development. Last year we launched a very successful update to our iOS and Android apps – a totally reengineered and redesigned experience – built from the ground up with the newest technologies. This doesn’t stop us from constantly extending our product, re-evaluating outdated technologies, and constantly pushing to become the world’s best. We are looking for engineers who love and understand .NET stack and seek the challenge of using cutting edge technologies to create a robust, scalable, and blazing-fast API. You will be expected to deliver high quality, well-designed, and thoroughly tested code within tight time constraints; so a solid understanding of OO design principles and modern testing practices will be crucial. You are expected to be fluent at explaining and justifying your decisions. Expertise in distributed platforms (like Hadoop, Cassandra, etc) is a major plus, but we expect candidates to be able to master these and many other technologies as we go. In addition, we expect superb attention to the details of performance and scalability of produced solutions (SQL queries, smart caching, code, and more). You will be expected to introduce proper measurements in production and constantly analyze them to verify set performance goals and suggest further improvements. Ultimately, we are looking for real technologists who have a great passion for creating the robust, scalable, and reliable back-end architecture required to support fantastic apps. We want innovative ideas on how to save our customer another 100 milliseconds waiting for results or how to architect the server side to support tens of thousands of requests a second.   Responsibilities: Candidates will join the mobile app scrum team with iOS, Android, and backend developers, and as part of their day-to-day responsibilities will: * Come up with the best suitable technology and architecture for their tasks * Work closely with all team members to understand full stack functionality and architecture * Communicate constantly with product owners to understand and measure business values of developed features * Contribute ideas (technological and product) to enhance the overall app experience * Address production issues of the system   Qualifications: Technologies of interest (we are not expecting you to have them all): * C# expert * Scripting (Python / Ruby / …) * WCF / Web API, IIS * Cassandra / Hadoop * Memcached * SQL * Analytics * A/B testing * Git Engineering topics of interest: * Clean architecture * API development techniques * Design-patterns (Gang of four) * Object oriented programming and design principles * Testing (unit/integration/system/...) * Automation of work process (CI, tools, etc) * Strafe-jumping like a pro in Quake 3 with your colleagues   Please note this role is open to both Thai and International candidates, however a good standard of English (both written and spoken) is a must.
